Luv2,
When they were still making them MSRP was $379. No idea what they'll bring on the secondary market.

As stated above, I wouldn't worry about any theoretical difference between the 2 actions. Aesthetically the No 1 wins hands down, but for shootability I much prefer the ghost ring on the No4. I would keep loads at or below the "Marlin" level according to Hornady. The mag length limits bullet choice, I have feeding problems with even the 400 A-frame, and at 8 lb 13 oz it's more suitable with the 300-350 grainers.
